| 摘要 |
<P>PROBLEM TO BE SOLVED: To provide a cellulose acylate solution showing a good surface state of a cellulose acylate film obtained by using the solution in a solution film-forming method, and a low peeling load. <P>SOLUTION: This cellulose acylate solution satisfies the following formulae (1) to (3) and contains the cellulose acylate having 50 ppm<S<500 ppm residual sulfuric acid radical (S is the content of sulfur atom of the residual sulfuric acid radical). The formulae (1) to (3) are; formula (1): 2.5≤A+B≤3, formula (2): 0≤A≤2.5, formula (3): 0.3≤B≤3 [wherein, A is the degree of substitution of acetyl group; and B is the total sum of the degree of substitution of 4-7C acyl groups]. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
